I’m cruising on the Sapphire Princess December 19. I am unaware of covid requirements, other than a vaccination card, showing completion of the covid vaccine, no boosters or online tests.
I had to cancel a 29 day cruise on the Majestic, which cruised Sept 20, due to the lack of a booster. That requirement was about a week before the cruise! I did cruise the first 4 days of that cruise, without being boosted.
i will be following up with my TA about this.
